Design of xASK-CodeSK system for Simultaneous Visible Light Wireless Information and Power Transfer

In the visible light communications, simultaneous light information and power transfer can be realized by using a solar panel as a receiver. Recently, IoT devices have been spreading rapidly, however, they often have limited energy capacity due to batteries. Therefore, optical wireless power transfer is in demand to increase operating time. In this paper, we propose a visible light communication system with simultaneous power transfer. The proposed system combines binary amplitude shift keying and code shift keying which selects K(
